A car travels at 15 m/s for 10 s.It then speeds up with a constant acceleration of 2.0 m/s² for 15 s.At the end of this time,what is its velocity? A)15 m/s B)30 m/s C)45 m/s D)375 m/s

Question

Quizplus · Accepted Answer

The car initially travels at 15 m/s. During the acceleration phase, its velocity increases by 2.0 m/s² for 15 seconds, resulting in an increase of 2.0 m/s² * 15 s = 30 m/s. Therefore, the final velocity is 15 m/s + 30 m/s = 45 m/s.
